Abstract:We have used NMR to determine the structure of acetylene (HC~CH) adsorbed at room temperature on small platinum particles by studying the l3c_13c, l3C_1H, and lH_1H dipolar interactions among the nuclei in the adsorbed molecules. We find a model of 77% CCH2 and 23% HCCH to be the only one consistent with all of our data. The C-C bond length of the majority species, CCH2, is determined as 1.44 ± 0.02 A, midway between a single and double bond, suggesting that both carbon atoms bond to the surface.
